BACKGROUND

The invention relates generally to a medical device, and more particularly to a medicament delivery device for delivering a medicament into a body of a patient.

Exposure to certain substances, such as, for example, peanuts, shellfish, bee venom, certain drugs, toxins, and the like, can cause allergic reactions in some individuals. Such allergic reactions can, at times, lead to anaphylactic shock, which can cause a sharp drop in blood pressure, hives, and/or severe airway constriction. Accordingly, responding rapidly to mitigate the effects from such exposures can prevent injury and/or death. For example, in certain situations, an injection of epinephrine (i.e., adrenaline) can provide substantial and/or complete relief from the allergic reaction. In other situations, for example, an injection of an antidote to a toxin can greatly reduce and/or eliminate the harm potentially caused by the exposure. Because emergency medical facilities may not be available when an individual is suffering from an allergic reaction, some individuals carry a medicament delivery device, such as, for example, an auto-injector, to rapidly self-administer a medicament in response to an allergic reaction.

To actuate such a medicament delivery device, however, the user may be required to execute a series of operations. For example, to actuate some known auto-injectors, the user must remove a protective cap, remove a locking device, place the auto-injector in a proper position against the body and then press a button to actuate the auto-injector. Failure to complete these operations properly can result in an incomplete injection and/or injection into an undesired location of the body. In certain instances, for example, users who have become confused in the operation of some known auto-injectors have inadvertently injected the medicament into their thumb by improperly positioning the auto-injector.

The likelihood of improper use of known medicament delivery devices can be compounded by the nature of the user and/or the circumstances under which such devices are used. For example, many users are not trained medical professionals and may have never been trained in the operation of such devices. Moreover, in certain situations, the user may not be the patient, and may therefore have no experience with the medicament delivery device. Similarly, because some known medicament delivery devices are configured to be used relatively infrequently in response to an allergic reaction or the like, even those users familiar with the device and/or who have been trained may not be well practiced at operating the device. Finally, such devices are often used during an emergency situation, during which even experienced and/or trained users may be subject to confusion, panic and/or the physiological effects of the condition requiring treatment.

Some known medicament delivery devices include printed instructions to inform the user of the steps required to properly deliver the medicament. Such printed instructions, however, can be inadequate for the class of users and/or the situations described above. Moreover, because some known medicament delivery devices, such as, for example, auto-injectors, pen injectors, inhalers or the like, can be compact, such printed instructions may be too small to read and comprehend during an emergency situation.

Some known medicament delivery devices include and electronic system to assist the user in setting the proper dosage and/or maintaining a compliance log. Such known medicament delivery devices and the accompanying electronic systems can be large and therefore not conveniently carried by the user. Moreover, such known medicament delivery devices and the accompanying electronic systems can be complicated and/or expensive to manufacture.

Thus, a need exists for a medicament delivery device and/or a medicament container that can be conveniently carried by a user, that provides instructions that can be easily understood by an untrained user in any type of situation, and that can be inexpensively manufactured.

SUMMARY

Medicament delivery devices are described herein. In one embodiment, an apparatus includes a label configured to be coupled to a medicament delivery device. The label includes a first surface and a second surface. The first surface is configured to be coupled to an outer surface of the medicament delivery device. The second surface includes a textual indicia. The label further includes an electronic circuit system configured to output an electronic signal.

FIGS.1 and2A-2C are a perspective view and partial cutaway front views, respectively, of an auto-injector1002 according to an embodiment of the invention. The auto-injector1002 is similar to the auto-injectors described in U.S. patent application Ser. No. 11/562,061, entitled “Devices, Systems and Methods for Medicament Delivery,” filed Nov. 21, 2006, which is incorporated herein by reference in its entirety. Accordingly, only an overview of the mechanical components and related operation of the auto-injector1002 is included below.

The auto-injector1002 includes ahousing1110 that defines agas chamber1120. Thehousing1110 has aproximal end portion1112 and adistal end portion1114. Abase1520 is movably coupled to thedistal end portion1114 of thehousing1110. Asafety lock1710 is removably coupled to thebase1520. As discussed in more detail herein, when thesafety lock1710 is coupled to thebase1520, the auto-injector1002 cannot be actuated. When thesafety lock1710 is removed from thebase1520, thebase1520 can be moved relative to thehousing1110, thereby actuating the auto-injector1002. Accordingly, to inject a medicament into the body, thedistal end portion1114 of thehousing1110 is oriented towards the user such that thebase1520 is in contact with the portion of the body where the injection is to be made. Thebase1520 is then moved towards theproximal end1112 of thehousing1110 to actuate the auto-injector1002.

The auto-injector1002 includes amedicament injector1210 and asystem actuator1510 disposed non-coaxially within thehousing1110. Themedicament injector1210 includesmultiple medicament vials1262, aplunger1284 movably disposed within eachmedicament vial1262, amovable member1312 engaged with eachplunger1284 and aneedle1212. Retraction springs1350 located within a portion of thebase1520 and thehousing1110 can push theneedle1212 back within thehousing1110 after injection. Thesystem actuator1510 includes acompressed spring1560, acompressed gas cylinder1412, and apuncturing mechanism1612 to dispel the contents of the compressedgas cylinder1412.

A status of the auto-injector1002 can be determined viastatus indicator1400, which can provide a view, such as via a UV blocking, photo-sensitive, and/or translucent window, into an interior of the housing1100. Viewable through the window can be a status of medicament carried byhousing1110, a location of a needle and/or injection apparatus for the medicament, and/or an activation status of the auto-injector1002. For example, if the medicament has aged to the point of discoloration, which aging might or might not render the medication useless, harmful, etc.,status indicator1400 can allow that situation to be determined. In certain exemplary embodiments, gas can escapehousing1110 viastatus indicator1400 and/or another opening in thehousing1110.

In use, when the auto-injector1002 is actuated, thepuncturing mechanism1612 punctures the compressedgas cylinder1412 allowing a pressurized gas to flow into thegas chamber1120. In response to a force produced by the pressurized gas on themovable member1312, themovable member1312 moves distally within thehousing1110. As a result, theneedle1212 is extended through thehousing1110. The movement of themovable member1312 also causes theplungers1284 to move within thevials1262, thereby expelling a medicament from thevials1262. The injection apparatus can be actuated by a fluid pressure, such as pressure provided by the compressed gas, which upon completion of its actuation duties can escape housing1100 via gas escape opening, such as viastatus indicator1400.

As shown, themedicament carrier1250 can hold each of thevials1262 and can travel withinsleeve1500.Medicament carrier1250 can comprise a plurality of channels adapted to receive medicament as it exits itsrespective vial1262, and direct medicament to acommon conduit9300.Medicament carrier1250 can interface with theneedle1212 and/oruse indicator7000. As shown inFIG. 2B, asmedicament carrier stop1251 contacts actuatorbar stop1300, medicament carrier hooks1252 can engage withengagement receivers7100 inuse indicator7000.

Referring toFIG. 2B, asgas chamber1120 continues to expand,medicament injector1210,movable member1312, and/orplungers1284 can continue moving until they complete their travel withinmedicament vials1262, thereby expelling a predetermined dose of medicament fromvials1262, out of theneedle1212, external tohousing1110, and/or into the patient. Asgas chamber1120 reaches its maximum size,medicament injector1210,movable member1312, and/orplungers1284 can continue moving until they complete their travel with respect tomedicament carrier1250, thereby causinggas release actuator1254 to engage withgas release valve1328. Engagement ofgas release actuator1254 withgas release valve1328 can cause withingas chamber1120 to exitgas chamber1120, discharge away from themovable member1312, and/or exhaust from the auto-injector1002 and/orhousing1110, such as viastatus indicator1400 and/or a gas escape port located onhousing1110.

Referring toFIG. 2B andFIG. 2C, as sufficient gas is vented fromgas chamber1120, the pressure applied by the gas ingas chamber1120 can decrease until the force applied by the gas onmedicament injector1210 is less than the force of retraction springs1350. Thus, retraction springs1350 can begin to expand, thereby movingmedicament carrier1250,vials1262, andmedicament injector1210 away frombase1520 and helping to exhaust gas fromgas chamber1120. Asmedicament carrier1250 moves,use indicator7000 can travel with it, due to the engaged relationship of medicament carrier hooks1252 andengagement receivers7100 and/orengagement catches7200 inuse indicator7000. Asuse indicator7000 moves away from thebase1520, theneedle sheath1213 can travel with it, thereby creating a gap between the sheath tip and the needle port, and thereby exposing a previously non-visible colored portion1521 of thebase1520 and/or providing an indication that the auto-injector1002 has been used (and likely substantially exhausted of its medicament), thereby discouraging any further attempts to use the auto-injector1002.

The auto-injector1002 includes anelectronic circuit system1920 to provide a predetermined sequence of electronic outputs during the use of the auto-injector1002. Theelectronic circuit system1920 is powered by a battery (not shown in FIGS.1 and2A-2C) and includes a processor (not shown in FIGS.1 and2A-2C), astart button1970, twoswitches1972A and1972B, aproximity sensor1974, twovisual output devices1958A and1958B and anaudio output device1956. The components of theelectronic circuit system1920 are operatively coupled by any suitable mechanism, such as, for example, a printed circuit board (not shown in FIGS.1 and2A-2C) having conductive traces.

Thestart button1970 is disposed on the proximal end of thehousing1110 and can be manually actuated by the user to begin the sequence of electronic outputs. Thefirst switch1972A is disposed on thedistal portion1114 of thehousing1110 adjacent thebase1520 and the lockingmember1710. The lockingmember1710 is configured to engage thefirst switch1972A such that when the lockingmember1710 is removed, as shown inFIG. 1, thefirst switch1972A changes states. In this manner, removal of the lockingmember1710 can trigger the processor to output a predetermined electronic output.

Similarly, thesecond switch1972B is disposed on thehousing1110 adjacent themedicament injector1210. Themedicament injector1210 is configured to engage thesecond switch1972B such that when themedicament injector1210 is moved distally within thehousing1110 thesecond switch1972B changes states. In this manner, the processor can be prompted to output a predetermined electronic output based on the position of themedicament injector1210.

Theproximity sensor1974 is disposed on thebase1520 and is configured to produce an output when thebase1520 engages the body. The proximity sensor can be, for example, a temperature sensor, an optical sensor or the like. In this manner, the processor can be prompted to output a predetermined electronic output when thebase1520 is positioned against the body.

The firstvisual output device1958A is disposed on the lockingmember1710. Similarly, the second visual output device1958B is disposed on the outer surface1111 of thehousing1110. Thevisual output devices1958A and1958B are in electronic communication with the processor and are configured to produce an output in response to an electronic signal output by the processor. Thevisual output devices1958A and1958B can be any suitable visual indicia, such as, light-emitting diodes (LEDs), liquid-crystal display (LCD) screens, optical polymers, fiber optic components or the like. In some embodiments, thevisual output devices1958A and1958B can be coupled to thehousing1110 and/or the lockingmember1710 by alabel1910.

Theaudio output device1956 is disposed within thehousing1110 such that it can project sound outside of thehousing1110. Theaudio output device1956 can be any suitable device for producing sound, such as a micro-speaker a piezo-electric transducer or the like. Such sound output can include, for example, an alarm, a series of beeps, recorded speech or the like. Theaudio output device1956 is in electronic communication with the processor and is configured to produce an output in response to an electronic signal output by the processor.

In use, the user activates the electronic circuit system by pushing thestart button1970 to activate the processor, thereby causing the processor to output a predetermined sequence of electronic outputs. In some embodiments, thestart button1970 can activate the processor by providing an input to the processor. In other embodiments, thestart button1970 can activate the processor by placing the battery (not shown in FIGS.1 and2A-2C) in electronic communication with the processor.

In some embodiments, upon activation, the processor can output an electronic signal to theaudio output device1956 thereby producing a first electronic output instructing the user in how to use the auto-injector1002. Such a message can state, for example, “please remove the safety tab.” Additionally, the firstvisual output device1958A can produce a flashing light to further indicate to the user where the lockingmember1710 is located. The processor can be configured to repeat the first audible instruction if the lockingmember1710 is not removed within a predetermined time period.

When the user removes the lockingmember1710, thefirst switch1972A changes states thereby triggering the processor to output an electronic output providing a second instruction to the user. The second instruction can be, for example, an audible speech output instructing the user to “please place the base of the device on the outer portion of your thigh.” The firstvisual output device1958A can produce a lighted output during this audible instruction, thereby visually indicating where thebase1520 is located and/or what portion of thebase1520 should be placed on the thigh.

When the user places thebase1520 against the body, theproximity sensor1974 provides an input to the processor, thereby triggering the processor to output an electronic output providing a third instruction to the user. The third instruction can be, for example, an audible speech output instructing the user to “push down on the top of the device to activate the injector.”

When the injection is completed, themedicament injector1210 is configured to engage thesecond switch1972B, thereby triggering the processor to output an electronic output providing a fourth instruction to the user. Such a post-use instruction can be, for example, an audible speech output instructing the user to seek further medical attention, providing instructions for the safe disposal of the auto-injector1002 or the like.

FIG. 3 is a schematic illustration of theelectronic circuit system1920 of the auto-injector1002. Theelectronic circuit system1920 includes aprocessor1950 operatively coupled to amemory device1954. Thememory device1954 can be configured to store processor-readable code1955 instructing theprocessor1950 to perform the functions described above. In some embodiments, the processor-readable code1955 can be modified and/or updated as circumstances dictate. Theelectronic circuit system1920 includes an input/output device1952 configured to receive electronic inputs from theswitches1972A and1972B, theproximity sensor1974 and/or thestart button1970. The input/output device1952 is also configured to provide electronic signals to the various output devices, such as thevisual output devices1958A and1958B and theaudio output device1956.

Theelectronic circuit system1920 also includes anetwork interface1953 configured to couple theelectronic circuit system1920 to a communications network. Such an arrangement can be used, for example, to download replacement processor-readable code1955 from a central network (not shown) to thememory device1954. Thenetwork interface1953 can also be configured to transmit information from theelectronic circuit system1920 to a central network, the user's home computer, the user's cell phone or the like.

FIG. 4 is a schematic illustration of amedical device2002 according to an embodiment of the invention. Themedical device2002, which can be, for example, a medicament delivery device such as an auto-injector, a pen injector, an inhaler, a transdermal delivery system or the like, includes ahousing2110 and alabel2910. Thelabel2910 is coupled to anouter surface2111 of thehousing2110. Thelabel2910 includes afirst surface2912, asecond surface2914 and anelectronic circuit system2920. Thefirst surface2912 is configured to engage theouter surface2111 of thehousing2110 to couple thelabel2910 to thehousing2110. In some embodiments, thefirst surface2912 can include an adhesive to fixedly couple thelabel2910 to thehousing2110. Thesecond surface2914 includes a textual indicia2916. The textual indicia2916 can include, for example, a description of the medicament delivery device, a source of the medicament delivery device and/or an instruction associated with the use of the medicament delivery device. Although thefirst surface2912 is shown as being opposite thesecond surface2914, in other embodiments, thefirst surface2912 and thesecond surface2914 can be adjacent each other and/or co-planar.

Theelectronic circuit system2920 is configured to output an electronic signal. As discussed in more detail herein, theelectronic circuit system2920 can include many components, such as, for example, a processor, a switch, a visual output device and/or an audio output device. The electronic signal can be, for example, an electronic signal communicated to an output device, such as, for example, a visual output device, an audio output device, a haptic output device or the like. In some embodiments, the electronic signal can be associated with an aspect of themedical device2002, such as an instruction associated with an initial use of themedical device2002. For example, in some embodiments, theelectronic circuit system2920 can output a text message to a display screen (not shown) disposed on themedical device2002 instructing the user in the use of themedical device2002. In other embodiments, theelectronic circuit system2920 can produce an audio output, such as recorded speech, instructing the user in the use of themedical device2002.

Although theelectronic circuit system2920 is shown as being disposed on thesecond surface2914 of thelabel2910, in other embodiments, the electronic circuit system can be disposed on thefirst surface2912 of thelabel2910. In yet other embodiments, theelectronic circuit system2920 can be disposed between thefirst surface2912 and thesecond surface2914 of thelabel2910. In yet other embodiments, thelabel2910 can include multiple discrete layers coupled together, within which portions of the electronic circuit system can be disposed.

FIG. 5 is a perspective view of an auto-injector4002 according to an embodiment of the invention. The auto-injector4002 is similar to the auto-injectors described in U.S. patent application Ser. No. 11/562,061, entitled “Devices, Systems and Methods for Medicament Delivery,” filed Nov. 21, 2006, which is incorporated herein by reference in its entirety. Accordingly, the mechanical components and operation of the auto-injector4002 are not described in detail herein.

The auto-injector4002 includes ahousing4110 having aproximal end portion4112 and adistal end portion4114. Thedistal end portion4114 of thehousing4110 includes aprotrusion4142 to help a user grasp and retain thehousing4110 when using the auto-injector4002. Said another way, theprotrusion4142 is configured to prevent the auto-injector4002 from slipping from the user's grasp during use. Abase4520 is movably coupled to thedistal end portion4114 of thehousing4110. Aneedle guard assembly4810 is removably coupled to thebase4520. Similarly, asafety lock4710 is removably coupled to thebase4520. To inject a medicament into the body, thedistal end portion4114 of the housing is oriented towards the user such that thebase4520 is in contact with the portion of the body where the injection is to be made. Thebase4520 is then moved towards theproximal end4112 of thehousing4110 to actuate the auto-injector4002.

FIG. 26 is a perspective view of the auto-injector4002 showing thehousing4110 in phantom lines so that the components contained within thehousing4110 can be more clearly seen. Similarly,FIG. 27 is a front view of the auto-injector4002 showing thehousing4110 in phantom lines. For clarity, the auto-injector4002 shown inFIGS. 26 and 27 show the auto-injector4002 without theneedle guard assembly4810′, thesafety lock4710′ and theelectronic circuit system4920. Additionally, the auto-injector4002 shown and described with reference toFIGS. 26-34 is presented to describe the mechanical components and operation of the device. Accordingly, the auto-injector4002 shown and described with reference toFIGS. 26-34 includes aneedle guard assembly4810′ that does not include a battery isolation tab4860 (see e.g.FIG. 12), asafety lock4710′ that does not include an actuator4732 (see e.g.,FIG. 13), and a base4520′ that does not include an actuator4538 (see e.g.,FIG. 14).

The auto-injector4002 includes amedicament injector4210 and amovable member4312 engaged with themedicament injector4210, each of which are disposed within thehousing4110. The auto-injector4002 also includes asystem actuator4510, acompressed gas container4412 and agas release mechanism4612. Themedicament injector4210 includes acarrier4250 that is movable within thehousing4110, amedicament container4262 and aneedle4212. Themedicament container4262 is coupled to thecarrier4250. Theneedle4212 is disposed within a needle hub portion of the carrier to allow theneedle4212 to be placed in fluid communication with themedicament container4262 during an injection event.

Themovable member4312 includes aproximal end portion4316 and adistal end portion4318. Theproximal end portion4316 includes asurface4322 that, together with thehousing4110, defines agas chamber4120. Said another way, thesurface4322 defines a portion of a boundary of thegas chamber4120. Thedistal end portion4318 is disposed within themedicament container4262. In use, themovable member4312 moves towards thedistal end portion4114 of thehousing4110, as indicated by arrow C inFIG. 26, in response to a force produced by a pressurized gas on thesurface4322 of themovable member4312. As a result, themovable member4312 and themedicament injector4250 are moved towards thedistal end portion4114 of thehousing4110, thereby exposing theneedle4212 from thehousing4110. Themovable member4312 then continues to move within themedicament container4262 to expel a medicament from themedicament container4262 through theneedle4212.

The auto-injector4002 is actuated by thesystem actuator4510, which is configured to move the compressedgas container4412 into contact with thegas release mechanism4612. Thegas release mechanism4612 punctures a portion of the compressedgas container4412 to release the pressurized gas contained therein into thegas chamber4120 defined by thehousing4110. Thesystem actuator4510 includes arod4540, aspring4560 and aspring retainer4570. Therod4540 has aproximal end portion4542 and adistal end portion4544. Theproximal end portion4542 of therod4540 is coupled to the compressedgas container4412. Thedistal end portion4544 of therod4540 is coupled to thespring retainer4570 by twoprojections4548, which can be moved inwardly towards each other to decouple therod4540 from thespring retainer4570, as discussed below.

Thespring4560 is disposed about therod4540 in a compressed state such that thespring4560 is retained by theproximal end portion4542 of therod4540 and thespring retainer4570. In this manner, therod4540 is spring-loaded such that when thedistal end portion4544 of therod4540 is decoupled from thespring retainer4570, the force of thespring4560 causes therod4540, and therefore thecompressed gas container4412, to move proximally as indicated by arrow D inFIG. 26 and into contact with thegas release mechanism4612.

The base4520′ defines anopening4522 configured to receive a portion of theprojections4548 when the base is moved towards theproximal end4112 of thehousing4110, as indicated by arrow E inFIG. 26. When theprojections4548 are received within theopening4522, they are moved together causing thedistal end portion4544 of therod4540 to be released from thespring retainer4570.

As shown inFIGS. 26 and 27, themedicament injector4210 defines a longitudinal axis Lm that is non-coaxial with the longitudinal axis Le defined by the compressedgas container4412. Accordingly, themedicament injector4210, thecompressed gas container4412 and thesystem actuator4510 are arranged within thehousing4110 such that the housing has a substantially rectangular shape. Moreover, the non-coaxial relationship between themedicament injector4210 and thecompressed gas container4412 allows the auto-injector4002 to be actuated by manipulating thebase4520′, which is located at thedistal end portion4114 of thehousing4110.

Prior to use, the auto-injector4002 must first be enabled by first removing theneedle guard4810′ and then removing thesafety lock4710′. As illustrated by arrow G inFIG. 28, theneedle guard4810′ is removed by pulling it distally. As described in more detail below, removal of theneedle guard4810′ also removes the isolation tab4860 (seeFIG. 12), thereby placing thebatteries4962 into electrical connection with the electronic circuit system4910 (not shown inFIGS. 26-34, for purposes of clarity). Similarly, as illustrated by arrow H inFIG. 29, thesafety lock4710′ is removed by pulling it substantially normal to the longitudinal axis Le of the compressedgas container4412. Said another way, thesafety lock4710′ is removed by moving it in a direction substantially normal to the direction that theneedle guard4810′ is moved. As described below, removal of thesafety lock4710′ also actuates the electronic circuit system4920 (not shown inFIGS. 26-34, for purposes of clarity). Theneedle guard4810′ and thesafety lock4710′ are cooperatively arranged to prevent thesafety lock4710′ from being removed before theneedle guard4810′ has been removed. Such an arrangement prevents the auto-injector4002 from being actuated while theneedle guard4810′ is in place.

As shown inFIG. 30, thesafety lock4710′ is a U-shaped member having afirst end4712 and asecond end4714. Thesecond end4714 of thesafety lock4710′ includes twoextended portions4716, each of which includes an inwardly facingprotrusion4718. When thesafety lock4710′ is in its first (or locked) position, theextended portions4716 extend around a portion of the base4520′ to space thebase4520′ apart from thedistal end portion4114 of thehousing4110. As shown inFIG. 31, theprotrusions4718 are configured engage a portion of the base4520′ to removably couple thesafety lock4710′ in its first position. Additionally, one of theextended portions4716 defines arecess4720 that receives thesheath retainer4840 when theneedle guard4810′ is in its first position.

Thefirst end4712 of thesafety lock4710′ includes alocking protrusion4722 that extends inwardly. As shown inFIG. 31, when thesafety lock4710′ is in its first position, the lockingprotrusion4722 extends between theprojections4548 of therod4540 and obstructs theopening4522 of the base4520′. In this manner, when thesafety lock4710′ is in its first position, thebase4520′ cannot be moved proximally to allow theprojections4548 to be received within theopening4522. The arrangement of thelocking protrusion4722 also prevents theprojections4548 from being moved inwardly towards each other. Accordingly, when thesafety lock4710′ is in its first position, the auto-injector4002 cannot be actuated.

Theouter surface4724 of thefirst end4712 of thesafety lock4710′ includes a series ofridges4726 to allow the user to more easily grip thesafety lock4710′. Theouter surface4724 of thefirst end4712 of thesafety lock4710′ also includes anindicia4728 to instruct the user in operating the auto-injector4002. As shown inFIG. 30, theindicia4728 includes a numeral to indicate the order of operation and an arrow to indicate the direction in which thesafety lock4710′ should be moved. In some embodiments, theindicia4728 can include different colors, detailed instructions or any other suitable indicia to instruct the user. In other embodiments, theindicia4728 can protrude from thesafety lock4710′ to aid the user when grasping thesafety lock4710′.

After being enabled, the auto-injector4002 can then be actuated by moving thebase4520′ proximally towards thehousing4110, as indicated by arrow I inFIG. 32. Additionally, as described below, movement of the base4520′ actuates the electronic circuit system4920 (not shown inFIGS. 26-34, for purposes of clarity).

As shown inFIG. 33, thebase4520′ defines twoopenings4536 that receive corresponding attachment protrusions4150 disposed on thedistal end portion4114 of thehousing4110. In this manner, the movement and/or alignment of the base4520′ relative to thehousing4110 is guided by the attachment protrusions4150 and theopenings4536. Each attachment protrusion4150 is secured within its correspondingopening4536 by alock washer4534. Thelock washers4534 each define anopening4535 that receives a portion of the attachment protrusion4150. Thelock washers4534 are disposed withinslots4533 defined by thebase4520′ so that theopenings4535 are aligned with the attachment protrusions4150. Theopenings4535 are configured to allow thelock washers4534 to move proximally relative to the attachment protrusions4150, but to prevent movement of thelock washers4534 distally relative to the attachment protrusions4150. In this manner, when the attachment protrusions4150 are disposed within theopenings4535 of thelock washers4534, thebase4520′ becomes fixedly coupled to thehousing4110. Moreover, after the base4520′ is moved proximally relative to thehousing4110, thelock washers4534 prevent the base4520′ from returning to its initial position.

The base4520′ also defines aneedle opening4532, arecess4526 and two retraction spring pockets4531. Theneedle opening4532 receives a portion of theneedle guard4810′ when the needle guard is in its first position. Additionally, when the auto-injector4002 is actuated, theneedle4212 extends through theneedle opening4532. The retraction spring pockets4531 receive a portion of the retraction springs.

As shown inFIG. 33, thebase4520′ includes two opposingtapered surfaces4524 that define anopening4522 configured to receive a corresponding tapered surface4550 of theprojections4548 when the base4520′ is moved proximally towards thehousing4110. When theprojections4548 are received within the taperedopening4522, they are moved together as indicated by arrows J inFIG. 32. The inward movement of theprojections4548 causes therod4540 to become disengaged from thespring retainer4570, thereby allowing therod4540 to be moved proximally along its longitudinal axis as thespring4560 expands.

Because therod4540 is coupled to the compressedgas container4412, when therod4540 is moved from its first (engaged) position to its second (actuated) position, thecompressed gas container4412 is moved proximally within thehousing4110 into engagement with thegas release mechanism4612.FIG. 34 shows the auto-injector in a second configuration, in which the compressedgas container4412 is engaged with thegas release mechanism4612. When in the second configuration, the compressed gas contained within the compressedgas container4412 is released to actuate themedicament injector4210.

The pressurized gas produces a force that causes themovable member4312 and themedicament injector4210 to move distally within thehousing4110. The movement of themedicament injector4210 causes theneedle4212 to extend fromdistal end portion4114 of thehousing4110 and thebase4520. This operation can be referred to as the “needle insertion” operation. When themedicament injector4210 has completed its movement (i.e., the needle insertion operation is complete), themovable member4312 continues to move themedicament container4262 distally within thecarrier4250. The continued movement of themedicament container4262 places theneedle4212 in fluid communication with themedicament container4262, thereby allowing the medicament to be injected. The force from the pressurized gas also causes themovable member4312 to move within themedicament container4262, thereby expelling the medicament through theneedle4212. This operation can be referred to as the “injection operation.” Upon completion of the injection, the pressurized gas is released from thegas chamber4120, thereby allowing themedicament injector4210 and themovable member4312 to be moved proximally within the housing. This operation can be referred to as the “retraction operation.”

The auto-injector4002 includes alabel4910 coupled to anouter surface4111 of thehousing4110. Thelabel4910 includes anouter layer4911, anintermediate layer4980 and an electronic circuit system4920 (seeFIGS. 7-9).FIG. 6 is a front view of the auto-injector4002 showing theouter layer4911 of thelabel4910 in phantom lines so that theintermediate layer4980 and anelectronic circuit system4920 can be more clearly seen. As shown inFIGS. 7-9, theouter layer4911, which, in some embodiments, can be constructed from paper, has afirst surface4912 and asecond surface4914 opposite thefirst surface4912.Multiple indicia4916 are disposed on thefirst surface4912. Theindicia4916 include atextual indicia4916A and twosymbolic indicia4916B. Thetextual indicia4916B can be written text describing the medicament delivery device, indicating a source of the medicament delivery device and/or instructing a user in the use of the medicament delivery device. Thesymbolic indicia4916B can include, for example, arrows, pointers, trademarks, symbols describing the use of the medicament delivery device or the like. Thelabel4910 is coupled to theouter surface4111 of thehousing4110 such that the portion of thefirst surface4912 including theindicia4916 is visible.

A portion of thesecond surface4914 of theouter layer4911 can be coupled to theouter surface4111 of thehousing4110 by any suitable method. For example, in some embodiments, thesecond surface4914 of theouter layer4911 includes an adhesive configured to bond theouter layer4911 to theouter surface4111 of thehousing4110. Other portions of thesecond surface4914 of theouter layer4911 are adjacent theintermediate layer4980 and portions of theelectronic circuit system4920. In this manner, theouter layer4911 of thelabel4910 retains the intermediate, or spacer,layer4980 and theelectronic circuit system4920 in a predetermined position against theouter surface4111 of thehousing4110.

Theouter layer4911 of thelabel4910 includesmultiple openings4917 adjacent theaudio output device4956. In this manner, sound waves produced by theaudio output device4956 can be transmitted to an area outside of thehousing4110. Similarly, theouter layer4911 of thelabel4910 includesopenings4918 adjacent the light emitting diodes (LEDs)4958A and4958B to allow the user to see the visual output. In some embodiments, theouter layer4911 of thelabel4910 can include a transparent portion adjacent theLEDs4958A and4958B to allow the user to see the visual output.

Theelectronic circuit system4920 includes a printedcircuit board4922 upon which amicroprocessor4950, twoLEDs4958A and4958B, twoswitches4972A and4972B and variouselectronic components4951, such as, for example, resistors, capacitors and diodes, are mounted. Theelectronic circuit system4920 also includes anaudio output device4956, such as, for example, a micro-speaker, coupled to theouter surface4111 of thehousing4110 adjacent the printedcircuit board4922. The printedcircuit board4922 includes asubstrate4924 upon which a series ofelectrical conductors4934, such as for example, copper traces, are etched. Thesubstrate4924 can be constructed from any material having suitable electrical properties, mechanical properties and flexibility, such as, for example Mylar®, Kapton® or impregnated paper.

A mask layer (not shown) is disposed over thesubstrate4924 to electrically isolate selected portions of theelectrical conductors4934 from adjacent components. Theelectrical conductors4934 operatively couple the above-mentioned circuit components in a predetermined arrangement. In this manner, theelectronic circuit system4920 can be configured to output, via theLEDs4958A and4958B and/or theaudio output device4956, a predetermined sequence of electronic outputs during the use of the auto-injector4002.

Power is supplied to theelectronic circuit system4920 by twobatteries4962 connected in series. The batteries can be, for example, three volt, “watch-style” lithium batteries. As shown inFIG. 9, each of thebatteries4962 has afirst surface4964 and asecond surface4966 opposite the first surface. Thefirst surface4964 can be, for example, an electrically negative terminal. Similarly, thesecond surface4966 can be an electrically positive terminal. As discussed in more detail herein, thebatteries4962 are positioned such that a firstelectrical contact portion4936 of the printedcircuit board4922 can be placed in contact with thefirst surface4964 of thebattery4962 and a secondelectrical contact portion4938 of the printedcircuit board4922 can be placed in contact with thesecond surface4966 of thebattery4962. In this manner, thebatteries4962 can be operatively coupled to theelectronic circuit system4920.

As shown inFIGS. 7 and 9, abattery isolation tab4860 is movably disposed between the firstelectrical contact portion4936 of the printedcircuit board4922 and thefirst surface4964 of one of thebatteries4962. Thebattery isolation tab4860 can be constructed from any electrically isolative material, such as, for example, Mylar®. As discussed in more detail herein, in this manner, thebatteries4962 can be selectively placed in electronic communication with theelectronic circuit system4920.

The intermediate, or spacer,layer4980 is disposed between theouter layer4911 and theelectronic circuit system4920. Theintermediate layer4980 includes openings (not shown) within which various components of the electronic circuit system, such as, for example, thebatteries4962 are disposed. Theintermediate layer4980 is sized to maintain a predetermined spacing between the various components included in thelabel4910. The intermediate layer can be constructed from any suitable material, such as, for example, flexible foam having an adhesive surface, polycarbonate or the like.

FIG. 10 is a front view of theelectronic circuit system4920 showing the arrangement of the various components (i.e., themicroprocessor4950,LEDs4958A and4958B, switches4972A and4972B,audio output device4956 or the like).FIG. 11 is a schematic illustration of theelectronic circuit system4920.

The operation of the auto-injector4002 and theelectronic circuit system4920 is now discussed with reference toFIGS. 12-14. The actuation of theelectronic circuit system4920 includes several operations that are incorporated into the standard procedures for using the auto-injector4002. In this manner, the user can actuate theelectronic circuit system4920 without completing any additional operations.

Prior to use, the auto-injector4002 is first enabled by removing theneedle guard4810 and the safety lock4710 (seeFIGS. 12 and 13). As illustrated by arrow AA inFIG. 12, theneedle guard4810 is removed by moving it distally. Theneedle guard4810 includes asheath retainer4840 and asheath4820. Thesheath4820 is configured to receive a portion of the needle (not shown) when theneedle guard4810 is in a first (or installed) position. Thesheath retainer4840 is coupled to thesheath4820 such that when thesheath retainer4840 is moved distally away from thebase4520 into a second (or removed) position, thesheath4820 is removed from the needle.

Thesheath retainer4840 includes anactuator4864 that is received by anopening4862 in theisolation tab4860. Accordingly, when thesheath retainer4840 is moved distally away from thebase4520, theisolation tab4860 is removed from the area between the firstelectrical contact portion4936 of the printedcircuit board4922 and thefirst surface4964 of one of thebatteries4962. In this manner, thebatteries4962 can be operatively coupled to theelectronic circuit system4920 when theneedle guard4810 is removed, thereby actuating theelectronic circuit system4920.

When actuated, theelectronic circuit system4920 can output one or more predetermined electronic outputs. For example, in some embodiments, theprocessor4950 can output an electronic signal associated with recorded speech to theaudible output device4956. Such an electronic signal can be, for example, associated with a .WAV file that contains a recorded instruction instructing the user in the operation of the auto-injector4002. Such an instruction can state, for example, “remove the blue safety tab near the base of the auto-injector.” The processor can simultaneously output an electronic signal to thefirst LED4958A, thereby causing thefirst LED4958A, which is located near thesafety lock4710, to flash a particular color. In this manner, theelectronic circuit system4920 can provide both audible and visual instructions to assist the user in the initial operation of the auto-injector4002.

In other embodiments, theelectronic circuit system4920 can output an electronic output associated with a description and/or status of the auto-injector4002 and/or the medicament contained therein. For example, in some embodiments,electronic circuit system4920 can output an audible message indicating the type of medicament contained in the auto-injector, the expiration date of the medicament, the dosage of the medicament or the like.

As illustrated by arrow BB inFIG. 13, thesafety lock4710 is removed by moving it substantially normal to the longitudinal axis of thehousing4110. Thesafety lock4710 has afirst end4712 and asecond end4714. When thesafety lock4710 is in its first (or locked) position, thesecond end4714 extends around a portion of the base4520 to space thebase4520 apart from thedistal end portion4114 of thehousing4110. Additionally, thefirst end4714 includes a locking protrusion (not shown) that obstructs portions of the system actuator (not shown) further preventing the base4520 from being moved proximally towards thehousing4110. Accordingly, when thesafety lock4710 is in its first position, the auto-injector4002 cannot be actuated.

In some embodiments, thesafety lock4710 includes anactuator4732 that actuates theelectronic circuit4920 to trigger a predetermined output or sequence of outputs when thesafety lock4710 is moved from the first position to a second (or unlocked) position, as shown inFIG. 13. More particularly, as shown inFIGS. 10,15 and16, theactuator4732 includes aprotrusion4730 that is received within afirst opening4928A defined by an actuation portion4926 of thesubstrate4924 when thesafety lock4710 is in the first position. The boundary4929 of thefirst opening4928A has a discontinuous shape, such as, for example, a teardrop shape, that includes a stress concentration riser4930. The discontinuity and/or the stress concentration riser4930 of the boundary4929 can be of any suitable shape to cause thesubstrate4924 to deform in a predetermined direction when theprotrusion4730 is moved relative to thefirst opening4928A.

As shown inFIGS. 15 and 16, thefirst opening4928A is defined adjacent anelectrical conductor4934 that, as discussed above, electronically couples the components included in theelectronic circuit system4920. Theelectrical conductor4934 includes afirst switch4972A, which can be, for example a frangible portion of theelectrical conductor4934. In use, when thesafety lock4710 is moved from the first position to the second position, theactuator4732 moves in a direction substantially parallel to a plane defined by a surface of the actuation portion4926 of thesubstrate4924. The movement of theactuator4732 causes theprotrusion4730 to move within thefirst opening4928A, as indicated by the arrow DD inFIG. 16. The movement of theprotrusion4730 tears the actuation portion4926 of thesubstrate4924, thereby separating the portion of theelectrical conductor4934 including thefirst switch4972A. Said another way, when thesafety lock4710 is moved to the second position, theactuator4732 moves irreversibly thefirst switch4972A from a first state (e.g., a state of electrical continuity) to a second state (e.g., a state of electrical discontinuity).

When theactuator4732 actuates theelectronic circuit system4920 as described above, theelectronic circuit system4920 can output one or more predetermined electronic outputs. For example, in some embodiments, theprocessor4950 can output an electronic signal associated with recorded speech to theaudible output device4956. Such an electronic signal can be, for example, associated with a recorded message notifying the user of the status of the auto-injector4002. Such a status message can state, for example, “The auto-injector is now enabled.” The processor can also simultaneously output an electronic signal to thefirst LED4958A, thereby causing thefirst LED4958A to stop flashing, change color or the like.

In some embodiments, theelectronic circuit system4920 can be configured to output the status message for a predetermined time period, such as, for example, five seconds. After the predetermined time period has elapsed, theelectronic circuit system4920 can output an audible message further instructing the user in the operation of the auto-injector4002. Such an instruction can state, for example, “Place the base of the auto-injector against the patient's thigh. To complete the injection, press the base firmly against the patient's thigh.” In some embodiments, the processor can simultaneously output an electronic signal to thesecond LED4958B, thereby causing thesecond LED4958B, which is located near thebase4520, to flash a particular color. In this manner, theelectronic circuit system4920 can provide both audible and visual instructions to assist the user in the placement and actuation of the auto-injector4002. In some embodiments, theelectronic circuit system4920 can be configured to repeat the instructions after a predetermined time period has elapsed.

After the auto-injector4002 is enabled and placed against the body of the patient, the auto-injector4002 is actuated by moving thebase4520 proximally towards thehousing4110, as illustrated by arrow CC inFIG. 14. Thebase4520 includes anactuator4538 that actuates theelectronic circuit4920 to trigger a predetermined output or sequence of outputs when thebase4520 is moved from a first position to a second position, as shown inFIG. 13. Theactuator4538 includes aprotrusion4539 that is received within asecond opening4928B (seeFIG. 10) defined by thesubstrate4924 when thebase4520 is in the first position. The configuration and operation of theprotrusion4539, thesecond opening4928B and the second switch4972B are similar to the configuration and operation of theprotrusion4730, thefirst opening4928A and thefirst switch4972A, and are therefore not described in detail.

When theactuator4538 actuates theelectronic circuit system4920, theelectronic circuit system4920 can output one or more predetermined electronic outputs. For example, in some embodiments, theprocessor4950 can output an electronic signal associated with recorded speech to theaudible output device4956. Such an electronic signal can be, for example, associated with a recorded message notifying the user that the injection is complete, instructing the user on post-injection disposal and safety procedures, instructing the user on post-injection medical treatment or the like. Such a status message can state, for example, “The injection is now complete. Please seek further medical attention from a doctor.” The processor can also simultaneously output an electronic signal to thefirst LED4958A, thereby causing thefirst LED4958A to stop flashing, change color or the like, to provide a visual indication that the injection is complete.

As described above, thebatteries4962 are positioned such that the firstelectrical contact portions4936 of the printedcircuit board4922 can be placed in contact with thefirst surface4964 of eachbattery4962 and the secondelectrical contact portion4938 of the printedcircuit board4922 can be placed in contact with thesecond surface4966 of eachbattery4962. As shown inFIGS. 10 and 17, the firstelectrical contact portions4936 each include a pair ofelectrical contacts4937 that are operatively coupled to theelectronic circuit system4920. Similarly, the secondelectrical contact portion4938 includes a pair ofelectrical contacts4939 that is operatively coupled to theelectronic circuit system4920.

The firstelectrical contact portions4936 and the secondelectrical contact portion4938 are monolithically constructed from the printedcircuit board4922.FIGS. 17-20 are perspective views showing the printedcircuit board4922 in various stages of manufacture.FIG. 21 is a flow chart illustrating a method5000 for manufacturing a flexible printed circuit board according to an embodiment of the invention. The illustrated method includes disposing a copper layer on thetop surface4925 of theflexible substrate4924 and etching the desired series of electrical conductors (not shown inFIGS. 17-20) at5002. A mask layer (not shown) is disposed on portions of thetop layer4925 of thesubstrate4924 to electrically isolate selected portions of the electrical conductors from adjacent components at5004. During this operation, theelectrical contacts4937,4939 are constructed.

The printedcircuit board4922 is then populated with the microprocessor, switches, output devices and/or other electronic components to form theelectronic circuit system4920 at5006. For clarity, the circuit components are not shown inFIGS. 17-20. After the printedcircuit board4922 is populated, the portion of theflexible substrate4924 forming the secondelectrical contact portion4938 is separated from the remainder of thesubstrate4924 at5008. As shown inFIG. 17, during this operation, aportion4923 of the boundary between the secondelectrical contact portion4938 and the remainder of thesubstrate4924 is left intact.

As shown by the arrow EE inFIG. 18, the secondelectrical contact portion4938 is then moved upwardly away from the remainder of thesubstrate4924 at5010. In this manner, the secondelectrical contact portion4938 is spaced apart from the firstelectrical contact portions4936. As shown by the arrow FF inFIG. 19, the portion of the secondelectrical contact portion4938 containing theelectrical contacts4939 is then folded so that theelectrical contacts4939 on the secondelectrical contact portion4938 are facing theelectrical contacts4937 on the firstelectrical contact portions4936, at5012. In this manner, opposingelectrical contacts4937,4939 are constructed on the printedcircuit board4922 without disposing electrical conductors on and/or etching multiple surfaces of the printedcircuit board4922.

Thebatteries4962 are then disposed between the firstelectrical contact portions4936 and the secondelectrical contact portion4938 at5014. Although not shown inFIG. 19, in some embodiments, a battery isolation tab of the type discussed above can be disposed between one of the batteries and the printedcircuit board4922. Once thebatteries4962 are in place, thetop layer4911 of thelabel4910 is disposed about the printed circuit board4922 (seeFIG. 20) to maintain the position of thebatteries4962 within the printedcircuit board4922, at5016. Thelabel assembly4910 is then coupled to the outer surface of the housing (not shown) at5018. Thelabel4910 is coupled to the housing with sufficient tension and/or stretch to maintain theelectrical contacts4937 in electrical communication with thefirst surface4964 of eachbattery4962 and to maintain theelectrical contacts4939 in electrical communication with thesecond surface4966 of eachbattery4962. In this manner, thebatteries4962 can be held in place in a printedcircuit board4922 devoid of springs, clips or other rigid members.

As described above, theaudio output device4956, can include, for example, a micro-speaker. In some embodiments, for example, theaudio output device4956 can include an RS-1511A micro-speaker manufactured by Regal Electronics, Inc.

Similarly, themicroprocessor4950 can be a commercially-available processing device dedicated to performing one or more specific tasks. For example, in some embodiments, themicroprocessor4950 can be a commercially-available microprocessor, such as the Sonix SNC 12060 voice synthesizer. Alternatively, themicroprocessor4950 can be an application-specific integrated circuit (ASIC) or a combination of ASICs, which are designed to perform one or more specific functions. In yet other embodiments, themicroprocessor4950 can be an analog or digital circuit, or a combination of multiple circuits.

Themicroprocessor4950 can include a memory device (not shown) configured to receive and store information, such as a series of instructions, processor-readable code, a digitized signal, or the like. The memory device can include one or more types of memory. For example, the memory device can include a read only memory (ROM) component and a random access memory (RAM) component. The memory device can also include other types of memory suitable for storing data in a form retrievable by themicroprocessor4950, for example, electronically-programmable read only memory (EPROM), erasable electronically-programmable read only memory (EEPROM), or flash memory.

FIG. 22 is a flow chart illustrating amethod5040 for manufacturing a medical device according to an embodiment of the invention. The medical device can be any medicament delivery device of the type discussed above, such as, for example, an auto-injector, a pen injector, an inhaler, or a transdermal delivery device. The medical device can also be a medicament container, such as, for example, a pill bottle, a blister pack an intravenous solution bag or the like. The illustrated method includes assembling the medical device,5042. After the medical device is assembled, an electronic circuit system is placed on an outer surface of the medicament delivery device,5044. The electronic circuit system can by any electronic circuit system of the type shown and described above. In some embodiments, the electronic circuit system is placed on the outer surface of the medical device in a predetermined orientation. For example, in some embodiments, the electronic circuit system can include openings, such as openings4928 that are aligned with mating portions of the medical device, such as, for example,protrusions4730,4538. In other embodiments, however, the electronic circuit system can be placed on the outer surface of the medical device in any orientation.

After the electronic circuit system is placed on an outer surface of the medical device, a label is coupled to the medical device,5046. The label, which can be, for example, a label containing a textual indicia, is coupled to the medical device such that a portion of the label is disposed about the electronic circuit system. In this manner, the coupling of the label to the medical device also serves to maintain the electronic circuit system in its position against the outer surface of the medicament delivery device.

FIG. 23 is a flow chart illustrating a method5060 for manufacturing a medical device according to an embodiment of the invention. The medical device can be any medicament delivery device of the type discussed above, such as, for example, an auto-injector, a pen injector, an inhaler, or a transdermal delivery device. The medical device can also be a medicament container, such as, for example, a pill bottle, a blister pack, an intravenous (IV) bag or the like. The illustrated method includes assembling the medical device,5062. The medical device is then sterilized using any suitable sterilization process,5064. In some embodiments, for example, such as those embodiments in which the medicament is epinephrine, the medical device can be sterilized by exposure to ethylene oxide (EtO) gas. In other embodiments, the medical device can be sterilized by exposure to gamma radiation. In yet other embodiments, the medical device can be sterilized by exposure to heat, such as for example, by placing the medicament delivery device into an autoclave.

In parallel with the manufacture of the medical device, the illustrated method includes constructing an electronic circuit system of the type shown and described above,5066. The electronic circuit system is then coupled to a label,5068, to form a label assembly. Because the circuit construction is done apart from the manufacture of the medicament delivery device, it is not subjected the sterilization process, which, in some instances, may damage the circuit components.

The illustrated method then includes placing the label assembly on the outer surface of the medical device,5070. The label assembly is then coupled to the outer surface of the medical device,5072. In some embodiments, the label assembly can be coupled to the medicament delivery device by an adhesive, an elastic fastener, a shrink wrap or any other suitable method.

While various embodiments of the invention have been described above, it should be understood that they have been presented by way of example only, and not limitation. Where methods described above indicate certain events occurring in certain order, the ordering of certain events may be modified. Additionally, certain of the events may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above.

For example, although thefirst surface4912 of thetop layer4911 of thelabel4910 is shown and described as being opposite thesecond surface4914 of thetop layer4911 of thelabel4910, in other embodiments, thefirst surface4912 and thesecond surface4914 can be adjacent each other and/or co-planar. Similarly, although thetop layer4911 of thelabel4910 is shown and described as covering substantially all of thehousing4110, in some embodiments, thetop layer4911 of thelabel4910 can cover only a portion of the housing.

Although thelabel4910 is shown and described as including atop layer4911, anintermediate layer4980 and a printedcircuit board4922, in some embodiments, the layers comprising thelabel4910 can be arranged in any suitable order. For example, in some embodiments, a multi-layered label can include a printed circuit board as an intermediate layer. In other embodiments, a multi-layered label can include a printed circuit board as the outer layer. Moreover, in yet other embodiments, the label need not include multiple layers. For example, in some embodiments, a label can include a single layer that includes an electronic circuit system and textual indicia.

Although theindicia4916 are shown and described as being visible (e.g., textual indicia and/or symbolic indicia), in some embodiments, a label can include indicia that are haptic. For example, in some embodiments a label can include Braille. In other embodiments, a label can include indicia having a distinct feel, such as for example, a particularly rough or smooth surface.

Although theelectronic circuit system4920 is shown and described as including a printedcircuit board4922 having aflexible substrate4924, in other embodiments, an electronic circuit system can include a rigid printed circuit board. In yet other embodiments, an electronic circuit system can include a printed circuit board having a substrate having at least a rigid portion.

Moreover, in some embodiments, an electronic circuit system need not include a printed circuit board. For example, in some embodiments, an electronic circuit system can include electronic components operatively coupled by any suitable method other than by a printed circuit board.

Similarly, although the components included in the electronic circuit system4920 (e.g., themicroprocessor4950, theLEDs4958A and4958B or the like) are shown and described as being operatively coupled byelectrical conductors4934, in other embodiments, the components can be operatively coupled without being physically connected. For example, in some embodiments, at least a portion of the components included in an electronic circuit system can be inductively coupled. In other embodiments, at least a portion of the components included in an electronic circuit system can be evanescently coupled.

Although theswitches4972A and4972B are shown and described as being “tear-through” switches that are monolithically formed from theelectrical conductors4934, in other embodiments, a switch can be formed separately from theelectrical conductors4934. For example, in some embodiments, an electrical circuit system can include a series of first electrical conductors having a first set of characteristics (e.g., the width, height, material from which the conductor is fabricated or the like) and a switch constructed from a second electrical conductor having a second set of characteristics different than the first set of characteristics. In other embodiments, a switch can be a separate component, such as, for example, a microswitch, that is mounted to the printed circuit board. In yet other embodiments, an electrical circuit system can include a “pop-out” switch that includes a biasing member to bias the switch in a predetermined state. In yet other embodiments, an electrical circuit system can include a switch that is disposed at a location other than on a printed circuit board.

Similarly, although theswitches4972A and4972B are shown and described as being irreversibly movable from a first state to a second state, in other embodiments, a switch can be reversibly movable between a first state and a second state. Moreover, in yet other embodiments, a switch can have more than two distinct states.

Although theactuators4732,4539 are shown and described as being configured to move in a direction substantially parallel to the surface of thesubstrate4924, in other embodiments, an actuator can be configured to actuate an electronic circuit system by moving in any direction. For example, in some embodiments a circuit actuator can be moved in a direction substantially normal to a portion of an electronic circuit system.

Similarly, although theactuators4732,4539 are shown and described as actuating theswitches4972A and4972B by tearing and/or deforming a portion of thesubstrate4924, in other embodiments, a switch can be moved from a first state to a second state without deforming the substrate. For example, in some embodiments, an electronic circuit system can include a printed circuit board having a substrate and a frangible switch tab disposed on the substrate. An electrical conductor and/or a switch can be disposed on the frangible switch tab, such that when the switch tab is removed from the substrate the switch is moved from a first state to a second state. In this manner, the switch can be actuated without tearing and/or deforming a portion of the substrate.

Although theactuators4732,4539 are shown and described as being included on thesafety lock4710 and thebase4520, respectively, in other embodiments, the actuators can be included on any component of a medicament delivery device. For example, in some embodiments, an auto-injector can include a start button having an actuator configured to actuate an electronic circuit system. In other embodiments, an auto-injector can include a movable member configured to move a medicament container and/or a needle within a housing of the auto-injector, the movable member including an actuator configured to actuate an electronic circuit system.

Although thesafety lock4710 is shown and described as being removed from thehousing4110 of the auto-injector4002 when in its second position, in other embodiments, a safety lock can remain coupled to the housing of an auto-injector when in its second position. For example, in some embodiments, a safety lock can be moved from its first position to its second position by rotating a portion of the safety lock.

Certain components of the auto-injector4002 are shown and described as being coupled together via protrusions and mating openings. The protrusions and/or openings can be disposed on any of the components to be coupled together and need not be limited to only a certain component. For example, thesafety lock4710 is shown and described as including anactuator4732 having aprotrusion4730 configured to be received within anopening4928A defined by thesubstrate4924. In some embodiments, however, the protrusions can be disposed on thesubstrate4924 and the mating openings can be defined by theactuator4732. In other embodiments, such components can be coupled together in any suitable way, which need not include protrusions and mating openings. For example, in some embodiments, an actuator can be operatively coupled to an actuation portion of a substrate via mating shoulders, clips, adhesive or the like.

Similarly, although certain components of the auto-injector4002 are shown and described as being constructed from multiple separate components, in some embodiments, such components can be monolithically constructed. For example, theneedle guard4810 and thebattery isolation tab4860 are shown and described as being constructed separately and then coupled together. In other embodiments, a needle guard and a battery isolation tab can be constructed monolithically.

Although the electronic circuit systems are shown and described above as being configured to output primarily audible and visual outputs, in other embodiments, an electronic circuit system can be configured to produce any suitable output. For example, in some embodiments, an electronic circuit system can produce a haptic output, such as a vibratory output produced by a piezo-electric actuator. In other embodiments, an electronic circuit system can produce a thermal output, produced by a heating or cooling element.

Similarly, the visual output devices shown and described above can include any suitable type of visual output device, such as, for example, a liquid crystal display, an organic polymer display, a fiber optic display. In this manner, the visual output produced by an electronic circuit system can include text messages, numerical indications of the dosage or the like.

Although the electronic circuit systems are shown and described above as outputting recorded speech in English, in other embodiments, the electronic circuit system can output recorded speech in any language. In yet other embodiments, the electronic circuit system can output recorded speech in multiple languages.

Although the electronic circuit systems are shown and described above as including a proximity sensor, in other embodiments, an electronic circuit system can include any suitable sensor for providing feedback to the electronic circuit system. For example, in some embodiments, the electronic circuit system can include a pressure sensor configured to sense the internal gas pressure within a gas-powered auto-injector. In this manner, the electronic circuit system can output an instruction and/or a status message when the internal gas pressure crosses a predetermined threshold. For example, in some embodiments, when the internal gas pressure rapidly increases, the electronic circuit system can output a message, such as, for example, “Internal gas chamber has been successfully punctured—injection is in process.”

Similarly, in some embodiments, the electronic circuit system can include a temperature sensor configured to sense the temperature of the medicament contained within the medicament delivery device. In this manner, the electronic circuit system can output an instruction and/or a status message when the medicament is too cold for effective delivery. For example, in some embodiments, when the medicament is too cold for effective delivery (this may occur, for example, if the medicament delivery device has been left outside overnight), the electronic circuit system can output a message, such as, for example, “Medicament is too cold—please briskly rub the auto-injector between your hands.”

Although thebatteries4962 are shown and described as having a first surface4964 (an electrically negative terminal) and a second surface4966 (an electrically positive terminal) opposite the first surface, in other embodiments the batteries can include a first surface and a second surface that are adjacent each other and/or co-planar. In other embodiments, an electronic circuit system can be powered by a battery having any shape and/or any number of surfaces. In yet other embodiments, an electronic circuit system can be powered by any suitable energy storage device, such as, for example, a capacitor, solar cell, spring actuated generator, or the like.

Although the medicament delivery devices have been shown and described above as being primarily single-use medical injectors, in some embodiments a medicament delivery device can include any suitable device for delivering one or more doses of a medicament into a patient's body. For example, in some embodiments, a medicament delivery device can be a pen injector containing multiple doses of a chronic-care medicament, such as, for example, insulin. In such embodiments, an electronic circuit system can output instructions associated with not only an initial use of the medicament delivery device, but also associated with repeated uses, dosage monitoring or the like. In other embodiments, a medicament delivery device can include a transdermal medicament delivery device, an inhaler or a nasal medicament delivery device.

FIGS. 24 and 25 show aninhaler6002 according to an embodiment of the invention. Theinhaler6002 includes ahousing6110 and amedicament container6262 movably disposed within thehousing6110. Themedicament container6262 includes a metering mechanism (not shown inFIGS. 24 and 25) configured to discharge a predetermined volume of medicament when theinhaler6002 is actuated.

Thehousing6110 has aproximal end portion6112 and adistal end portion6114. Anlabel6910, which includes at least a portion of anelectronic circuit system6920, is disposed on anouter surface6111 of thehousing6110. As described above, a portion of thelabel6910 can include a textual indicia6916. Similar to the electronic circuit systems shown and described above, theelectronic circuit system6920 is configured to output at least one electronic signal associated with the user of theinhaler6002. Theelectronic circuit system6920 includes a microprocessor (not shown), amicrospeaker6956 and anLED6958. Theelectronic circuit system6920 also includes amotion sensor6976, the function of which is discussed in more detail below.

Thedistal end portion6114 of thehousing6110 includes amouthpiece6212 about which aprotective cap6710 is disposed. Prior to use, theinhaler6002 is first enabled by removing theprotective cap6710, as shown by the arrow GG inFIG. 25. Theprotective cap6710 includes anactuator6732 that actuates theelectronic circuit system6920 to trigger a predetermined output or sequence of outputs when theprotective cap6710 is removed. In some embodiments, theactuator6732 can include a protrusion that is received by an actuation portion of theelectronic circuit system6920, in a similar manner as described above. In other embodiments, theactuator6732 can be configured to engage a microswitch that can be repeatedly moved between a first state and a second state.

When actuated, theelectronic circuit system6920 can output one or more predetermined electronic outputs. For example, in some embodiments, theelectronic circuit system6920 can output an audible message via themicrospeaker6956 instructing the user to “vigorously shake the inhaler for five seconds.” The processor can simultaneously enable themotion sensor6976.

Upon receiving a predetermined input from themotion sensor6976, which can be any sensor suitable for detecting the rapid motion of theinhaler6002, the processor can then send an electronic signal to produce a second audible message. Such a message can state, for example, “the inhaler is now sufficiently shaken and is ready for use.” In some embodiments, theelectronic circuit system6920 can also output an instruction associated with the correct placement of theinhaler6002. For example, theelectronic circuit system6920 can output an audible message stating “please place the mouthpiece in your mouth and firmly press down on the medicament container.” Theelectronic circuit system6920 can also simultaneously output a signal to theLED6958 to provide a visual indication of where themouthpiece6212 is located.

After theinhaler6002 is enabled and placed within the mouth of the patient, theinhaler6002 is actuated by moving themedicament container6262 distally withinhousing6110, as illustrated by arrow HH inFIG. 25. In some embodiments, themedicament container6262 can include an actuator (not shown) that actuates theelectronic circuit6920, in a manner similar to those described above, to trigger a predetermined output or sequence of outputs. For example, in some embodiments, the processor can output an electronic signal associated with recorded speech to themicrospeaker6956. Such an electronic signal can be, for example, associated with a recorded message notifying the user that the injection is complete, instructing the user on post-injection procedures, instructing the user on post-injection medical treatment or the like. Such a status message can state, for example, “The injection is now complete.”

In other embodiments, a medicament delivery device can include a transdermal medicament delivery device, such as for example, a medicament patch. In such embodiments, an electronic circuit system can be configured, for example, to output instructions associated with the enablement, placement and/or removal of the transdermal medicament delivery device. For example, in some embodiments, the electronic circuit system can be actuated by removing a protective barrier that seals the portion of the device that contacts the skin.

Although the medical devices are shown and described above as being medicament delivery devices, such as, for example, medical injectors, inhalers or the like, in other embodiments, a medical device can include a medicament container, such as, for example, a pill bottle, a blister pack or the like.

Although various embodiments have been described as having particular features and/or combinations of components, other embodiments are possible having a combination of any features and/or components from any of embodiments where appropriate.
